For consumers seeking extra assurance of olive oil quality, here is a list of the olive oils that are enrolled in the North American Olive Oil Association's (NAOOA's) About Olive Oil Quality Seal program for random testing and certification.
The About Olive Oil Quality Seal program is the nation's largest and most complete olive oil testing and certification program. We purchase olive oil from supermarkets in the USA and Canada and test multiple times per year for adherence to the physico-chemical purity and quality standards set by the International Olive Council (IOC).
Brands that are part of the About Olive Oil Quality Seal program may bear this mark in either black and white or color. It is also possible that a product may be certified, but choose not to put the seal on the label (check out the FAQ on the seal program below).
As of January 15, 2023, the list is as follows:

How does the AboutOliveOil.org Seal Program work?
Participants in the AboutOliveOil.org Seal Program must agree to have us randomly test their products, which we sample from store shelves, and submit the samples to certified independent laboratories. The oils are tested to ensure that they meet or exceed the physico-chemical standards set by the International Olive Council to ascertain purity and quality. Participants pay a fee to participate in the program and license the AboutOliveOil.org Seal for use on their packaging. It does not mean that we test every bottle or even every lot. However, the penalty for getting caught is severe. If we can confirm that a product we have tested is not authentic, the company is required to conduct a recall of the licensed products from all stores across North America.
Do you test all brands?
No. We only test bottles of companies that agree to take part in the program. The program is currently only open to members of the North American Olive Oil Association.
Does the fact that an olive oil does not have your seal mean that the olive oil is not authentic?
The answer is emphatically no. According to a study conducted by scientists from the FDA in a study published in 2015 that the risk of purchasing a bottle of adulterated EVOO is low (less than 5%). The scientists randomly sampled 88 bottles of EVOO that they purchased from supermarkets and online stores, and did not find a single instance of adulteration. We invite you to read more stories related to olive oil quality on our blog. So even if a product does not have a certification seal, you should feel confident you are getting authentic products, especially if you buy from a retailer you trust, select a brand you know, and/or do not pay a price that is “too-good-to-be-true.”
The brand I usually buy does not have your seal…when will you test it?
We only test brands that agree to be part of our program. Please inquire with the brand and suggest that they might join.
I just purchased a bottle from a company whose name is listed on your webpage of certified brands, but the bottle does not have the seal on the label. Does that mean it is not authentic?
No. There are a couple of reasons why this may be the case. First, the AboutOliveOil.org Quality Seal program is product specific—not company specific. Companies have to pay the fee for each separate named product. A company might agree to pay the fee for their best-selling item, e.g., “Premium EVOO,” but not for a product that does not have wide distribution or high sales, e.g. “Organic Limited Edition EVOO.”
Second, companies in the program are not required to put the AboutOliveOil.org seal on their labels. Many are content just to have the seal listed on the website or share the information with retailers because labels get crowded and they may wish to use the space for other information.
